. IMPROVEMENT IN MORSE TELEGRAPH-REGISTERS.

Specification forming part of Letters Pa ent No. 147,186, dated February3, 1874; application filed May 2, 1873.

To all whom it may concern:

Be it known that I, JOHN E. SMITH, of the city, county, and State of NewYork, have in vented certain Improvements in the Morse Register for usein Electro-lvlagnetic Telegraphs, of which the following is aspecification This invention is mainly designed for use in district andfire-alarm telegraphs, although it may be employed for recording anytelegraphic characters composed wholly of dots and spaces. The inventiongenerally consists in an automatic Morse register, made self startingand stopping by a simple device, which causes the marking or embossinglever to act directly on the train of clockwork that moves the ribbon ofpaper.

[11 the accompanying drawing, which forms part of this specification,Figure 1 represents a plan of a Morse register constructed in accordancewith my invention; Fig. 2, a side view of the same,and Fig. 3 alongitudinal vertical section on the irregular line a; 00.

Similar letters of reference indicate corresponding parts.

A is a wooden or other suitable base for supporting the apparatus; andB, the frame of a Morse register, which differs in the followingrespects from other instruments of that description. Thus, instead ofthe fly usually employed at the fast end of the train of clockwork, Isubstitute a pallet, D. This pallet regulates the motion of theclock-work, and allows it to start suddenly with nearly full speed. Theend of the lever F, which carries the embossing-style, is extendedunderneath the roller G, and to its upper surface is fixed a pad, E, ofrubber or other elastic material.

\Vhenever the style is moved by the action of the electro-magnet W, tomark the paper ribbon, the elastic pad or spring E is simultane ouslypressed against the roller G, thereby stopping the clock-Work, andholding it in check as long as the magnet W- remains charged. Itaccordingly follows that only dots can be recorded by an instrument thusconstructed. The drum and weight for giving motion to the clock-work arenot shown in the drawing. The lever F may be made flexible, and arrangedto press against any of the wheels of thetrain with like results, or anin dependent lever and magnet may be used for this purpose. The pad alsomay be placed on the clock-work, instead of on the lever F. Either ofthese I regard as equivalents of the arrangement shown in the drawing.

\Vhen used on a long line, the register may be operated by means of arelay and local battery, precisely like the ordinary Morse in strumentbut for a short distance, one simple circuit only is required, and thebattery may be located wherever it is most convenient.

What is here claimed, and desired to be secured by Letters Patent, is

1. The pad or spring E, in combination with the lever F of anelectro-magnet and the clockwork of a recording-telegraph, substantiallyas and for the purpose described.

2. The pallet D, in combination with the pad or spring E, the lever F,and the clockwork of a recording-telegraph, essentially as hereinset-forth.
